The third year of junior high school is one to ask for help!! The question of the first year of high

Normal. I'm a sophomore in high school this year, and I chose science. At that time, when I was in junior high school, I went to a preparatory class, and then I was stunned by physics, and I was not a very bad student, and I was scared that I couldn't accept it for a while.

But then I found out that because I went to the preparatory class and overestimated my ability, the effect was very unsatisfactory, but as long as I calmed down and tried to concentrate on listening to the teacher, it didn't matter if I understood it or not, I would learn it again in the first year of high school, and after the start of school, in order to overrun junior high school and high school, I generally spoke slowly, so I didn't have to worry too much.

As above, I hope it helps.

In fact, you don't need to worry too much, when you make the transition from the third year of junior high school to the first year of high school, there will be some differences between the knowledge of books, the way the teacher lectures, the difficulty and amount of homework and junior high school. To give you some advice on learning mathematics, physics and chemistry (personal opinion, exclusive to Sunshine Baby SY, for reference only):

After the start of school, prepare a notebook for each course, which is used to extract the types of questions that the teacher talks about in class (especially mathematics and physics), the valuable mistakes in the homework (I don't understand the solution method, the knowledge points are missing, in fact, the time in high school is relatively tight, and I personally recommend that you can use the way of cutting and pasting, anyway, you won't look at many test papers in the future, so it is better to leave the valuable ones), the key topics and representative topics in the process of the teacher's lecture. The most important thing is that after doing this, you should make good use of this valuable resource and go through it often, especially if you read a few questions a day for a few weeks before the exam, and you will have something to gain by the time the exam comes.

The most important thing in science is to do more questions, and it is important to insist on doing questions, but you must also sort out the questions at the same time, otherwise many of them will be done in vain. When the teacher talks about the problem, you should write down the solution process, even if you are correct, because you may get a different solution.

You have to memorize chemistry more, understand mathematics and physics, and when you don't understand, you must ask the teacher after class, which is really useful, but you must ask after your own thinking, otherwise the thinking will still not be able to keep up. Most teachers will be happy to answer your questions, so don't be afraid to ask again and again if you don't understand it. If you ask more questions, your own learning enthusiasm will increase, and you will remember more deeply what the teacher tells you individually.

I have written so much, I hope it will help you, and you can ask me if you have any questions.

It was the same when I was a freshman in high school, but it became easier as time went on.

That's how you learn things, and you won't find it difficult after a long time.

I'm going to be in my third year of high school now, and I think it's pretty easy to get a first year of high school.

Learning is a slow process, everything is difficult at the beginning, when you get started, you will find it very easy, I wish you can get out of the psychological barrier, open your arms to high school.

Take it easy. I can't eat hot tofu in a hurry. Grasp the basics first. It would be much better to build the foundation.

I took the first class of my freshman year of high school three times, the Tianyuan Cup once, you once at this time, and the first class in high school.

In fact, the main thing is to change the learning method, from the original simulation to thinking. It's good to get used to it for a while.

It's okay, as long as you follow the teacher in the first year of high school, you must believe in yourself now.

Truth be told, you're scaring yourself.

Read more books, it's not difficult.

According to Veda's theorem (the relationship between roots and coefficients), the sum of the two roots is equal to b, and the product of the two roots is equal to c, so b+c 5.

Directly turn inequality into equation.

That is, 2 and 3 are the solutions of the equations.

Substituting yields 4+2b+c=0

9+3b+c=0

The solution yields b = -5 c = 6

Let's understand the relationship between the three quadratics.

As can be seen from the title, x is between 2 and 3, which means that the two roots of x are 2 and 3, so according to Veda's theorem, b -5, c 6, so b c 1

Hehe, classmate, don't worry. First of all, you have to believe in yourself and think that you must be the best.

Secondly, the body is very important. Only with a good body can you learn better. Then, don't learn so much at once, take your time.

Don't gnaw on yourself so much at once, you won't be able to digest it. Also, the weak subjects have to be made up, but the strong subjects cannot be put down.

You can't just ignore it at all, because you will lose your advantage, and this is more than worth the loss.

Relationships are seen as people. If you are good to others, others will be good to you. So think more about others, and it will improve!

While not addictive to gaming, reduce the amount of time you spend playing games. Because you are a student with little self-control.

In the end, you must believe in yourself, and you will definitely succeed!

I'm a junior in high school, but I'm going back this year, so I'll give you some advice.

1. There is no need to study during the holidays, especially after the high school entrance examination. The reason why you say that, firstly, because you study intermittently and without teaching aids, it is actually useless to strengthen your learning effect. The basic knowledge of high school is not difficult, but it is difficult to master and apply.

So it's okay to follow the teacher in the future, after all, the knowledge that started in the first year of high school is easy to get on the road, so don't worry about it at all. If you learn half-heartedly, it is easy to get distracted or arrogant in formal class, and the effect is not good.

I was busy in high school, so if you play well now and relax your mood completely, it will be easier to enter the state in the future, otherwise you will not learn well or play well, and your mood will be affected.

You say that you don't have tenacity, in fact, it's completely understandable, after all, we are still young, we all want to play, don't force yourself too hard, just relax and sleep your mind. Around me, the more you reach the third year of high school, the more you don't study during the week, because you are usually too busy, too tired, and need to combine work and rest. In normal times, you don't learn at all, so don't have psychological baggage.

2. I recommend you to exercise more. When I got to high school, because there was no physical education test, everyone didn't exercise. And if you get up early and go to bed late, you will be even more lazy if you are under pressure to study.

As a result, our weight rises and our physique decreases. Even my classmates were not in good health throughout their senior year of high school, so they studied more money to maintain their health.

So be sure to exercise, especially in the first and second years of high school that are not too busy.

3. Interpersonal relationships look at your environment. I grew up in a small city and the people were very nice. I haven't seen my classmates like bullies on TV, so as long as you compare your heart with your heart and treat others sincerely.

Relationships are important, especially as you reach adulthood, so don't shy away from them. The friendship of high school classmates is the most precious, without the mixing of interests, and it is very pure. Don't ask for a bunch of friends, just one or two confidants, and the ones in the class are all your friends.

Apologize first if you make a mistake, speak frankly, and have a lively temperament. People will accept you. But the most important thing is self-confidence!

4. I'm just like you, and I'm not addicted to playing games. If you are afraid of getting addicted, don't touch it. You know, I haven't played an online game in 3 years. One I don't like spending money online, and the other I'm afraid I'm addicted. I simply don't touch it.

But I only play RPGs, I don't spend too much money, and I guarantee the time. The love for the game has also eased a lot.

I'm repeating it now, and I'm very uncomfortable. I didn't work too hard in my freshman and sophomore years of high school, and the results after my efforts in my third year of high school were not good. Every inch is golden, I want you to remember.

There is no need to press yourself too hard in the first and second years of high school, but you must have solid knowledge and do your best. Otherwise, the taste of regret is really heart-wrenching.

Do you know why the grades in the repeater class are so good and the discipline is so good? It's not because they're a year longer than you, it's that they've already tasted that and they're starting over.

I bless you with all my heart, and I bless myself as well.

First of all, you first stabilize your emotions and sort out your thoughts, the high school entrance examination is nothing, but it is a turning point for you to be admitted to your ideal high school.

First: you have to be aware of time, first bitter and then sweet;

Third: If you don't understand, you must ask, you can't understand everything, otherwise you can defeat the invincible opponents in the world;

Fourth: progress with classmates, but also a combination of work and rest, of course, this means that when you finish your homework, you watch TV or listen to **, or go shopping with family or friends on the eve of the exam, buy food, eat and relax;

In the end, you must do your best to destroy the circle during the exam, and realize that you will be able to achieve success on your own, and don't think about the way to do it, which will harm you.

Don't worry, the high school entrance examination will not be as rare as the Hongzu second model exam, because the high school entrance examination contains the graduation exam, I believe the teacher also said these words, I didn't know that the test was not good, and I didn't know that there was a relationship to cover the disadvantages, through this time, I just knew that I still had ** to improve, and I would do the second model paper ...... elsewhere in the next monthAnyway, we will do the second mold roll of various districts and counties, so many will be useful to sit down! Trust you! Come on!!

The unsaturated unchanged and the rest will not.

The a in the title is the whole set of real numbers. So cr a is an empty set, so cr a and b are empty sets.

If a is the set of all positive real numbers, then d is correct.

The collation inequality is -xa+x +4x+3>0

then it becomes a primary function about a.

When -x>0.

Make it meet the meaning of the question then x +4x+3>0

The solution is x<-3 or -10 and -x*4+x +4x+3>0 is solved to x>0

When there is x=0, the topic is also satisfied.

So to sum up.

The value of x can be x<-3 or x>-1
